Sewer Sealing Cushions, Pipe-Bypass

This new series of sewer sealing cushions simplifies and accelerates the repair work – the cushions are self-fixing, the bypass DN 250 – DN 600 does not need any pump running. The water can be drained off geodetically (only by head) in large quantities directly through the sewer sealing cushion.

In the core there is a plastic pipe. Optionally the internal tube can be completely blocked by a second cushion or as a world-wide novelty: running water can be led through the construction or repair space trouble-free and safe and this with bypass diameters of 250 – 600 mm.

The advantages are obvious: Time saving by simple handling, cost reduction through failure of pumps (a head will do), more flexibility e.g. in the open excavation site with tube extensions.

Of course all devices are field-tested in our Research and Test Centre.
For your safety.

This possibility is suitable in case the construction site shall be kept free of water only for a short time. The internal bypass-tube is blocked with a LAMPE sewer sealing cushion Type 1 or 2. The discharge of the queued water can be done very quickly after the work has been finished.

However, the accumulated water can also be led by way of tube extensions over a longer distance through the construction site.
